== Introduction ==
SBC Diva can be populated with DWM WiFi/Bluetooth combo plugin to easily add wireless connectivity.
In order to enable the bluetooth, the correct device tree configuration must be passed to the kernel. The sbcd comes with two possible devicetree configurations. The default one enables the uart1 UART1 and therefore the bluetooth and wifi module. The other configuration instead, enables the can interface and disables the uart1UART1.
'''Note:''' make sure to pass the correct devicetree configuration.
== Wifi ==
To enable the wifi, the correct gpio pin must be configured. Once this has been done, the wlan0 interface should become accessible.
The gpio pin can be enabled as follow:
<pre>
echo 114 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio114/direction
echo 1 > /sys/class/gpio/gpio114/value
</pre>
E.g
<pre class="board-terminal">
root@diva:~# echo 114 > /sys/class/gpio/export
root@diva:~# echo out > /sys/class/gpio/gpio114/direction
root@diva:~# echo 1 > /sys/class/gpio/gpio114/value
